Can I test mobile responsiveness with this skill?

Yes, the skill includes tools to resize the viewport and emulate different devices, allowing you to capture screenshots and verify layouts across mobile, tablet, and desktop resolutions.

Does this support headless mode?

Yes, you can configure the MCP to run in headless mode by adding the --headless flag during the 'claude mcp add' setup process.

Can I monitor API calls with this skill?

Yes, the skill provides tools to list and inspect network requests, allowing you to verify that API calls are being made correctly and check their status codes and response data.

How do I handle element interactions if the UI changes?

It is recommended to re-run the take_snapshot tool after any interaction that modifies the DOM to ensure you have the most up-to-date UIDs for subsequent commands.

What is the benefit of using snapshots over screenshots?

Snapshots provide the page's accessibility tree and unique element IDs (UIDs), which are necessary for Claude to interact with specific elements accurately, whereas screenshots are primarily for visual verification.
